def find_service_name():

    protocolname = 'tcp'

    for port in [80, 25]:

        print 'Port:%s =>service name:%s' % (port, socket.getservbyport(port, protocolname))

        print 'Port:%s =>service name:%s' % (53, socket.getservbyport(53, 'udp'))

if __name__ == '__main__':

    find_service_name()

运行结果如下：
